Im trying to define which aftermarket x pipe should I add t my Cs2 w PSE to make It louder when valves are open, Both Cargraphic and FVD work with its valves, but don't know what kind of sound will develop each one of these. Does any one have heard both so can describe the difference between them?

 

If you get an X pipe you are essentially getting rid of your PSE and replacing it with either of your above choices.

Did you consider adding the Sharkwerks exhaust - it eliminates the side mufflers , makes the car sound much more aggressive and you still retain your centre PSE muffler

 

With Fvd center muffler bypass BES 991 150 00skr x and with Cargraphic silencer replacement x it is possible to keep PSE. The se are the two options I'm considering, I had understood they are X pipes, buy I might be wrong naming it.

 

As per the fvd website description (I'm assuming Cargrsphics same thing) ; the exhaust can be a "direct replacement for the factory Porsche Sport Exhaust". So you are replacing the centre PSE muffler. You still use stock side mufflers, tips and headers. You would still retain the side PSE mufflers though (I'm not sure how different these are compared with stock side mufflers)

 

What I like about these two options is that you keep the PSE button, so you can have the car in louder or normal sound.
If you also change the side mufflers for Sharkerks or similar bypass it will be also louder when you have the PSE off.
For me the option of having it loud or quiet is important. But when it will be loud, I want it to be very intense, that's why my original question about the difference between fvd and Cargraphic.
